| 摘 要： | 本文提出了状态估计的带权重最小二乘数学模型，用少量实测节点水压和管段流量估计所有节点水压，用于管网的状态模拟，采用附加节点流量伪测量数据，解决了解的惟一性问题．采用Marquardt法求解数学模型，收敛迅速，模型的解稳定．算例分析表明，估计的精度较高，能满足管网实时模拟的要求。

| Abstract: | A state estimation model, mended weighted least square model, in which pseudo data of nodal consumptions are involved is proposed to estimate all nodal pressures making use of some nodal pressure or pipe flows for state simulation of water distribution network, and the problem of unique solution is disposed. Marquardt method is selected to dissolve the model, and the process of iteration is fast and steady. Calculation shows that the precision of estimated variables is great enough for state simulation of water distribution network. |
